Looks good so far! Really cool ability design. Though, I would have read this as a shield ability at first glance without knowing what it did— (in WoW, at least) a hard-edge bubble like that usually represents a safe, shielded area (like Power Word: Barrier). I think that, combined with the outward motion of the energies inside the bubble, is giving the impression of it being a protected zone.
Is a really nice touch, but I didn’t notice it until I was frame-stepping through. Maybe it could build up more or last longer?
Also, if this is Void, try to involve some aggressive, chunky elements. These are the best examples from your board— really sharp and sinister vs wispy and soft. I actually noticed that Naaru element because I went to go screencap it as a good example of shape for Void, haha
(same disclaimer as other thread— I’m not judging these entries at the end of the day but just giving feedback :D)
